I have to boot with -f to make LAN works

[Pink Waters]

I noticed on my system that I have to always boot with -f and ignore boot caches so LAN works.

i rely on RealtekRTL81xx.kext but it seems not to load if i didn't boot with -f

what can cause that ?

The realtek kext is obviously not present in your prelinked kernel and you need to rebuild it. Maybe some conflicting extension prevents it from being rebuilt.

You can use this script if you aren't sure how to do it. It will also show you errors during the process, if there are any.

Ok, thanks for your reply, I ran the script from terminal with root access, and here is the the log: 

Edit: the only thing mentioned in the log about the kext is: kext com.lnx2mac.driver.RealtekRTL81xx  909000 is in exception list, allowing to load

The log looks fine, the signature and exception list warnings are normal with 10.9.

 

You can check if the kext is really loaded with kextstat | grep -i realtek and if it is not, try loading it manually with sudo kextload /path/to/kext.

 

If it still won't work, try this driver by Mieze, it should perform better anyway.

Thank you so much, the driver you suggested worked like a charm.

Thank you!
